Further, the second rotating member 301 includes an inner rotating ring 301a rotatably connected to the base 102, an outer rotating ring 301b fixedly connected to the inner rotating ring 301a, and a through cavity 301c penetrating the inner rotating ring 301a and the outer rotating ring 301 b; the inner rotating ring 301a can rotate, and when the inner rotating ring 301a rotates, the outer rotating ring 301b can be driven to synchronously rotate, and the through cavity 301c is used for installing the locking conductive piece 302.
The locking conductive member 302 includes a conductive strut 302a slidably disposed inside the through cavity 301c, a force-receiving plate 302b fixed to the outer side of the conductive strut 302a, a locking spring 302c abutting against the force-receiving plate 302b, and a locking head 302d disposed at the end of the conductive strut 302a, so that when the top end of the lightning arrester 700 is suspended on the inclined conductive hook 202, the bottom end of the lightning arrester 700 contacts and pushes the locking head 302d in the process of rotating the lightning arrester 700 to a vertical state, so that the locking head 302d drives the inner rotating ring 301a and the outer rotating ring 301b to rotate through the conductive strut 302a, and in the process of rotating, the force-receiving plate 302b presses the locking spring 302c in the process of rotating, because the locking conductive member 302 is converted from the inclined state to the vertical state, and because the lightning arrester 700 is converted from the inclined state to the vertical state, the distance between the bottom end of the lightning arrester 700 and the locking head 302d is shortened, and in the process, the bottom end of the lightning arrester 700 pushes the conductive strut 302a through the locking head 302d, and the bottom end of the lightning arrester 700 moves in the direction away from the lightning arrester 700.
Further, the locking head 302d is provided with a corresponding groove 302d-1, the bottom of the locking head 302d corresponding to the groove 302d-1 is provided with a positioning hole 302d-2, one end of the corresponding groove 302d-1, which is far away from the supporting beam 103, is provided with an opening 302d-3, during the rotation of the lightning arrester 700, the bottom end of the lightning arrester 700 enters the inner side of the corresponding groove 302d-1 from the opening 302d-3, one end of the corresponding groove 302d-1, which is far away from the opening 302d-3, is provided with an arc-shaped contact surface 302d-4, and after the bottom end of the lightning arrester 700 contacts the arc-shaped contact surface 302d-4, the locking head 302d is pushed to swing towards the supporting beam 103, and simultaneously the inner rotating ring 301a and the outer rotating ring 301b are driven to rotate.
The positioning hole 302d-2 is formed at the end of the corresponding groove 302d-1 far from the opening 302d-3, and the diameter of the positioning hole 302d-2 is the same as the diameter of the arc contact surface 302d-4, when the locking head 302d and the conductive sliding column 302a reach the vertical state, the bottom end of the lightning arrester 700 corresponds to the positioning hole 302d-2, in this case, the locking spring 302c pressed by the force plate 302b pushes the force plate 302b, so that the conductive sliding column 302a pushes the locking head 302d toward the bottom end of the lightning arrester 700, so that the bottom end of the lightning arrester 700 enters the inner side of the positioning hole 302d-2, at this time, the inner rotating ring 301a and the outer rotating ring 301b cannot rotate because the bottom end of the lightning arrester 700 is inserted into the positioning hole 302d-2, and the lightning arrester 700 cannot rotate itself because of being inserted into the inner side of the positioning hole 302d-2, thereby completing the installation of the lightning arrester 700.
Further, the first rotating member 201 includes a socket ring 201a rotatably connected to the top plate 104, an external connection rod 201b fixed to the socket ring 201a, and a synchronization ring 201c connected to the socket ring 201a through the external connection rod 201 b; the conductive hook 202 includes a conductive member 202a fixed to the socket ring 201a, a connection bar 202b installed at one end of the conductive member 202a, and a hook opening 202c provided at the other end of the conductive member 202 a.

Wherein the position of the conductive hook 202 corresponds to the position of the conductive sliding column 302a, and when the conductive hook 202 is pulled to be perpendicular to the ground by the lightning arrester 700, the conductive sliding column 302a is pushed by the bottom end of the lightning arrester 700 to be perpendicular to the ground.
In this embodiment, as shown in fig. 2, a lightning arrester 700 is further disclosed, in which a hanging hole 702 is formed in a top conductive member 701, so as to be hung on a hook opening 202c, and a bottom conductive member 703 is cylindrical, and has a diameter slightly smaller than that of the positioning hole 302d-2, so that the bottom conductive member 703 can enter the inner side of the positioning hole 302 d-2.

In order to maintain the inclined state of the locking conductive member 302 when the arrester 700 is not mounted, the second resilient member 303 is provided, and in a natural state, since the second spring 303d abuts against the pressing plate 301d and the circular ring 303c is further provided with the limiting piece 303e, the pressing plate 301d is abutted against the limiting piece 303e by the second spring 303d, so that the inner rotating ring 301a and the outer rotating ring 301b do not rotate, at this time, the locking conductive member 302 is maintained in an inclined state, and the end of the conductive strut 302a to which the locking head 302d is mounted is inclined in a direction away from the supporting beam 103.
